General Specifications

Standard Specifications (Oxygen Analyzer)
n
Measurement Object: Oxygen concentration in combustion exhaust gas and mixed gas (excluding
inflammable gases)
Measurement System: Zirconia system
Measurement Range: 0.01 to 100 vol% O
Output Signal: 4 to 20 mA DC (maximum load resistance 550 Ω)
Setting Range: Any setting in the range of 0 to 5 through 0 to 100 vol% O
range
Display Range: 0 to 100 vol% O
Warming-up Time: Approx. 20 min.
Repeatability: (Excluding the case where the reference gas is by natural convection) ± 0.5% F.S. ;
range from 0 to 5 vol% O
from 0 to 25 vol% O
Linearity: (Excluding standard gas tolerance and the case where the reference gas is by natural
convection) (Use oxygen of known concentration (with in the measuring range) as the zero
and span calibration gases.)
pressure within ± 4.9 kPa
pressure within ± 0.49 kPa
pressure within ± 0.49 kPa
Drift: (Excluding the first two weeks in use and the case where the reference gas is by natural
convection.)
Both zero and span ± 2% F.S. /month
Response Time: Response of 90% within 5 seconds.
(Measured after gas is introduced from calibration gas inlet and analog output starts
changing.)
Safety, EMC, and RoHS conformity standards of ZR22G, ZR802G
Installation altitude: 2000 m or less
Installation category: (IEC61010); II
Pollution degree: (IEC61010); 2
Measurement category: O (other)
Note · Installation category, called overvoltage category, specifies impulse withstanding voltage. Category II is for
electrical equipment.
· Pollution degree indicates the degree of existence of solid, liquid, gas or other inclusions which reduce dielectric
strength. Degree 2 is the normal indoor environment.
